Dosteen Engineering Solutions supplied more than 200 Dubai Metro fire rated roller shutters for the Green and Red Line, a Government of Dubai project delivered for the Roads and Transport Authority (RTA), to support fire compartmentation across the metro facility. The shutters were integrated with the Fire Alarm Control Panel as part of the project’s fire and life-safety strategy. Read the full Green & Red Line Dubai Metro case study.
The project was designed and managed by W.S. Atkins as architect and consultant, with JT Metro, ICGL, Fino International, and Linder Depa as the main contracting entities. Dosteen’s scope covered supply of fire rated roller shutters for the lobby area and openings across the facility that required controlled closure for compartmentation purposes, in compliance with Dubai Metro and UAE fire safety requirements.
The Challenge of Fire Compartmentation in Transit Buildings
The Green and Red Line Dubai Metro project required compliance with stringent fire and life-safety requirements across the metro facility. Meeting those requirements in a public transit environment involves specific considerations that go beyond the standard demands of commercial or residential construction.
Why Openings Matter in Fire Strategy
A building’s fire strategy is built around the principle of compartmentation: dividing the structure into defined zones so that fire and smoke are contained within the area of origin, slowing their spread and keeping evacuation routes clear for as long as possible. Solid construction achieves this in walls and floors, but openings present a different challenge.
Lobby areas, circulation zones, and operational access points in large-scale facilities cannot always be permanently sealed. They need to remain open during normal operation and close in a controlled manner when a fire event occurs. Without a reliable, rated closure mechanism at each of these openings, even a well-designed compartmentation strategy has gaps that can compromise the entire fire strategy in an incident.
The selection and correct integration of rated closures at each opening is therefore one of the most technically consequential decisions in the fire and life-safety design process. Getting it right requires choosing a product with the correct fire resistance rating for the designated opening, integrating it correctly with the fire alarm system, and ensuring it is maintained in a state of genuine readiness throughout the building’s operational life.
The Demands of Public Transit Environments
Public transit buildings carry a combination of characteristics that make fire and life-safety compliance particularly demanding. They operate continuously, with high volumes of people moving through them at all hours. Their layouts include large open circulation areas, interconnected platforms, concourses, and access points that require careful compartmentation design. They are subject to authority oversight and inspection requirements that go beyond those applied to many commercial projects, and they require ongoing compliance with the fire safety standards applicable to public infrastructure.
For the Green and Red Line Dubai Metro, these factors combined to make the fire and life-safety requirements a central and non-negotiable element of the project specification from the outset.
How Fire Rated Roller Shutters Support Life Safety
Fire rated roller shutters provide a controlled, rated closure at openings that must remain accessible during normal operation. Understanding their role in a building’s fire strategy requires understanding two distinct functions: compartmentation of the opening itself, and integration with the building’s fire alarm system.
Compartmentation of Openings
A fire rated roller shutter, when closed, forms a physical barrier at the opening it covers. The fire resistance rating of the shutter defines how long it is tested to resist the passage of fire and, where applicable, smoke across that opening under defined conditions. In a compartmentation strategy, each rated shutter contributes to maintaining the integrity of the compartment boundary at its designated opening for the duration of its rated performance period.
This is the function that makes fire rated roller shutters the appropriate choice for large openings in lobby areas and circulation zones, where a rigid fire wall cannot be used and a swinging fire door would be impractical given the width of the opening. The shutter closes across the full width of the opening, maintains the compartment boundary, and protects the evacuation route on the other side.
Dosteen’s fire protection systems cover fire rated shutters, fire and smoke curtains, and fire rated doors and windows, all specified and installed to UAE Civil Defence and NFPA standards. For the full range of roller shutters supplied and installed by Dosteen, see the roller shutters solutions page.
Integration with the Fire Alarm Control Panel
A fire rated roller shutter that operates in isolation from the building’s fire alarm system is not part of the fire strategy. It is a standalone product. Integration with the Fire Alarm Control Panel means the shutter becomes a component of the building’s coordinated fire alarm response, closing when the alarm sequence triggers the closure of rated openings in the designated compartment.
The specific sequence, trigger logic, and control interface depend on the fire alarm system design and the requirements of the project’s fire strategy. The practical outcome is that when a fire event is detected and the alarm responds, the shutters at designated openings close as part of an engineered response, not as a manual or independent action. On the Green and Red Line Dubai Metro project, Dosteen’s fire rated roller shutters were integrated with the Fire Alarm Control Panel as part of delivering the required fire protection performance across the facility.
What Dosteen Delivered on the Green & Red Line
Dosteen supplied more than 200 fire rated roller shutters for deployment across the lobby area and openings across the Green and Red Line Dubai Metro facility that required controlled closure for compartmentation. The shutters were specified to CSI specification reference 083323 - for full specification detail, see Dosteen’s CSI specifications page.
The reason for selecting Dosteen’s fire rated roller shutters was straightforward: the systems were required to enhance fire compartmentation, meet Dubai Metro and UAE fire safety requirements, and support improved protection for both assets and occupants across the facility. The shutters’ integration with the Fire Alarm Control Panel was a specific and non-negotiable requirement of the project scope.
The outcome of the supply was that the required operational, fire protection, and integration performance was achieved across the full quantity of units. The project was completed for the Government of Dubai, Roads and Transport Authority, with W.S. Atkins as architect and consultant.

What the Project Demonstrates About Dosteen
The Green and Red Line Dubai Metro project illustrates a specific combination of capabilities that defines Dosteen’s position as a fire protection systems supplier on major public and infrastructure projects.
Supplying more than 200 fire rated roller shutters correctly specified for each designated opening, integrated with a Fire Alarm Control Panel, and delivered in compliance with Dubai Metro and UAE fire safety requirements on a Government of Dubai project is not a standard commercial installation. It requires a supplier with the technical knowledge to specify correctly, the manufacturing and supply capability to deliver at scale, and the compliance processes to meet the documentation and approval requirements of a government infrastructure project.
Dosteen’s fire protection systems capability extends across fire rated shutters, fire and smoke curtains, and fire rated doors and windows, all manufactured and installed to UAE Civil Defence and NFPA standards. Periodic inspection and testing programmes and Civil Defence recertification support are part of the company’s ongoing service offering for fire protection systems, ensuring that systems remain compliant and operational throughout the building’s life.
These capabilities are underpinned by ISO 9001:2015, ISO 45001:2018, and ISO 14001:2015 certified operations and more than 25 years of engineering presence across the UAE, Oman, and the wider GCC. The Dubai Metro project is one data point in a project record that spans residential, commercial, industrial, and government sectors across the region.
Maintaining Compartmentation Integrity Across the Building Lifecycle
In continuous-use public facilities, compartmentation performance must last for the full operational life of the building. Correct product selection and installation are essential, but they do not secure that outcome on their own.
Three interconnected stages determine the result. At specification, each designated opening is assigned the fire resistance rating that its role in the fire strategy requires. At integration, the closure is coordinated with the fire alarm system so that it operates as part of the building’s response. After handover, periodic inspection and testing confirm that it remains ready for use.
The stages depend on one another. A correct rating has limited value if integration is incomplete, and sound integration has limited value if readiness is not maintained. The lifecycle view carries particular weight in high-occupancy transit environments, where openings must stay accessible during normal use but close reliably during a fire event.
Frequently Asked Questions
1. How were fire rated roller shutters used for fire compartmentation on the Green & Red Line Dubai Metro?
Dosteen supplied more than 200 fire rated roller shutters for the lobby area and openings across the Green and Red Line Dubai Metro facility that required controlled closure for compartmentation. The shutters were integrated with the Fire Alarm Control Panel to support the required fire protection performance as part of the project’s overall fire and life-safety strategy.
2. Why are fire rated roller shutters used for openings in transit buildings?
Large openings in transit buildings, including lobby areas and circulation of access points, need to remain operational during normal use and close in a controlled, rated manner when a fire event occurs. A fire-rated roller shutter provides this function, closing across the full width of the opening and maintaining the compartment boundary. On the Green and Red Line project, the shutters were selected to enhance fire compartmentation and comply with Dubai Metro and UAE fire safety requirements.
3. What does integrating a fire rated roller shutter with a fire alarm control panel involve?
Integration means the shutter becomes part of the building’s coordinated fire alarm response rather than operating independently. When the fire alarm sequence triggers the closure of rated openings in a designated compartment, the shutters close as part of that engineered response. The specific trigger logic and control interface depend on the fire alarm system design and the project’s fire strategy requirements.
4. Does Dosteen provide inspection and testing for fire protection systems after supply?
Yes. Dosteen’s ongoing service for fire protection systems includes periodic inspection and testing programmes, maintenance, and Civil Defence recertification support.
